Gestational hypertension disorders and breast cancer

Pregnancy is considered a "window of susceptibility" for breast cancer risk because changes to the breast during pregnancy may alter susceptibility to developing the disease later in life. Associations between pregnancy conditions and breast cancer risk may provide insight into how pregnancy relates to later cancer development. Some previous studies have found that women who experienced a gestational hypertensive disorder, including gestational hypertension, pre-eclampsia and eclampsia, have a reduced risk of breast cancer. In a recent analysis, Sister Study investigators examined whether history of a gestational hypertensive disorder was associated with breast cancer risk among women who have given birth at least once. They found that having a history of a gestational hypertensive disorder was not associated with breast cancer risk.
